How To Fix AD546 - Table & (too many generically buffered fields)

SAP Error Message - Details

• Message type: E = Error

• Message class: AD - Data Dictionary application messages

• Message number: 546

• Message text: Table & (too many generically buffered fields)

What causes this issue?

The number of fields to be generically buffered (entry in the
table's technical settings) is greater than or equal to the number of
key fields in the table. This is not acceptable. Only the contents of
key fields are written to the buffer during generic buffering so that
it does not make sense for the number of fields to be greater than the
number of key fields. If the number of fields to be buffered is the
same, the buffering type is 'partial buffering' and not 'generic
buffering'.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

You may not remove key fields from the table as long as a conflicting
number is entered in the technical settings for fields to be
buffered. If you want to remove key fields from the table, you should
correct the technical attributes accordingly. The table will continue
to have the status 'partially active' for as long as there is such an
inconsistency.

• What is the cause and solution for SAP error message AD546 - Table & (too many generically buffered fields) ?

  The SAP error message AD546, which states "Table & (too many generically buffered fields)," typically occurs when a table in the SAP system has too many fields that are set to be generically buffered. This can lead to performance issues and is a limitation within the SAP database buffering mechanism.
  Cause:
  
  Too Many Generically Buffered Fields: The error arises when a table has more than the allowed number of fields that can be generically buffered. This is a limitation imposed by the SAP system to ensure efficient data retrieval and memory management.
  Table Configuration: The configuration of the table may have been set to buffer too many fields generically, which is not optimal for performance.
  
  Solution:
  
  
  Review Table Buffering Settings:
  
  Go to the Data Dictionary (SE11) and check the buffering settings of the table in question.
  If the table is set to be buffered, consider changing the buffering type. You can switch from generic buffering to full buffering or no buffering, depending on the use case.
  
  
  
  Reduce the Number of Buffered Fields:
  
  If the table has too many fields set for generic buffering, you may need to remove some of these fields from the generic buffer configuration.
  Focus on buffering only those fields that are frequently accessed and necessary for performance.
  
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes that may provide additional guidance or updates regarding this error. SAP Notes can provide patches or recommendations for specific issues.
  
  
  
  Testing:
  
  After making changes to the buffering settings, test the application to ensure that performance is acceptable and that the error does not reoccur.
  
  
  
  Consult with Basis Team:
  
  If you are unsure about making changes to the buffering settings, consult with your SAP Basis team. They can provide insights into the impact of these changes on system performance and stability.
  
  
  
  Related Information:
  
  
  Buffering Types:
  
  No Buffering: The table is not buffered at all.
  Full Buffering: All records of the table are buffered.
  Generic Buffering: Only certain fields are buffered, which is useful for tables that are read frequently but updated less often.
  
  
  
  Performance Considerations: 
  
  Properly configuring table buffering can significantly impact the performance of SAP applications. Over-buffering can lead to memory issues, while under-buffering can lead to increased database access times.
  
  
  
  SAP Documentation: 
  
  Refer to the official SAP documentation for more details on table buffering and performance optimization.
  
  
  
  By addressing the configuration of the table and ensuring that it adheres to SAP's limitations on buffered fields, you can resolve the AD546 error and improve the overall performance of your SAP system.
